MOLD-INSERT-FEEDING MECHANISM.

Application filed March'l,

To all whom t may concern.'

Be it known that I, DICK M.; Vn'sEY, a citizen of the United States, residing at Fort l/Vayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Mold-Insert-Feeding Mechanisms, of which the following is a specification.

The invention relates to mechanisms for feeding inserts into molds, and it is particularly directed to means for feeding upon the pins of a rubber-heel mold the washer inserts that are embedded in the heel to act as abutments for the heads of nails or other means to attach the heel to the shoe or boot.

The object of the invention is to provide a simple mechanism by which the washer inserts arey effectively and automatically fed upon the pins of a rubberheel mold, thus accomplishing a large saving over the hand feed method commonly in use.

The invention consists in vertically arranged guiding members vupon which' the vwasher inserts are stacked and which are adapted to register'with the washer supporting pins of a heel mold and a movable mem- .ber in cooperative relation tothe guidingA members and having washer supporting means thereon.

The invention is illustrated in simple form in the accompanying drawings in which Figure 1 is a perspective view of a mechanism embodying the invention; Fig. 2 an elevational View of the guide lmembers and supporting frame; Fig. 3 a bottom plan view of the same; Fig. 4 a plan view of the valve supporting member; Fig. 5 a cross-section of the sameon line 5-5 of Fig. 4; Fig. 6 a cross-section on line 6 6 of Fig. 4; Fig. 7 a plan view of the valve member supported on its supporting member; Fig. 8 a fractional view, partly in section, of the'mechanism illustrating the method of supporting 45' the stacks of washers on the guide members;

Fig. 9 a similar view illustrating the rela tive position of the parts after' a washer has been released; Fig. 10 av plan View of one of the stack supporting members; Fig. 11 an enlarged plan view of a washer; Fig. 12 a central cross-sectional view of the same and Fig. 13 another form of washer having the invention applied thereto.

In the drawings I vhave illustrated the invention as applied to a single unit for the deposition of a set of washers simultaneously upon the pins of a single heel cavity in a von the said'reduced ends.

1923. serial No. 622,055.

duced ends of which a support 3 is' detachably secured by the feet 4 that are threaded The feet are adapted to support the frame at the proper height relatively to the heel mold 5. Guide rods 6 depend from the top member 1 and they are arranged in exact accordancewith the arrangement of the pins 7 that project upwardly from the heel mold. The latter pins are reduced at their upper ends to form shoulders 7a thereon upon which the washers 8 will lodge when released from the frame. The washers are placed on the guide rods 6 in any convenient manner. Each washer is formed with a central boss 8a or 8by (Fig. 13) for abutting the washer above it in a stack and thereby space the washers in the stack for the'purpose described later.

Where the support 3 is solid, as in the present embodiment, apertures 9 are formed therein through which the lower ends of the guide rods 6 extend axially, the apertures beingl of suflcient diameter to permit the washers t0 pass through them readily. The

only function of themeniber 3 is to support the controlling valve or slide 10, hence it may be in any desiredform.

In the present illustration the controlling slide or valve 10 is pivoted at 11 to the support 3, a revoluble-movement of the slide` l 1n a single unit being convenient but not essential, it being apparent that the slide may have any relative movement desired. Apertures 12 are formed inthe slide and are arranged in exact accordance with the arrangement ofthe guide rods so that when the slide is moved in proper direction the apertures will be brought into register with the guide rods axially, and to permit this axial registration to occur each aperture 12 is formed with a slotted extension 13 in which the associated guide rod 6 is operative. In the inactive position of the slide shown in Fig. 8 the guide rods are inthe slots 13.V

Then the slide is moved in properY direction the said movement causes the axial alinement or registration of the apertures and the guide rods. A stop 15 on the support 3, operative in a slot 16, limits the latter movement of the slide.

Adjacent to each aperture 12 a forked member 14- is secured to the slide, the forked poftion of each member 14 being elevated sufficiently to allow the same to pass over a washer, the forks passing onto opposite sides of the guide rod and engaging the bottom of the washer next above and thereby supporting the stack of washers on the rod. In the inactive or normal position of the slide the lowermost washer of each stack contacts with the upper face of the slideover the slots 13. The instant the apertures 12 in the slide axially register with the guide rods `and hence axially register with the washers on the rods, the lowermost washer of each stack drops through the aperture onto the pin below it; the forked members have already engaged under the washers nextabove the lowermost washers and hence support the rstacks of washers on the several guide rods. The reverse movement of the slide withdraws the stack supporting meinbers and causes the slots 1?) to move under the same.. `When the supporting members have disengaged from the stacks, the stacks drop down into contact with the slide, and the device is ready for another releasing operation.

It is apparent that any number of sets of the guiding members may be supported on a frame and the slide extended so that the lowermost washers of the several stacks shall be released simultaneously, thus feeding the washers to a plurality of heel forms in a mold, the general practice being to construct the mold with a large number of heel-forming cavities so that a large number of heels shall be produced at each use of the mold.

Various modifications in the structure and in the arrangement of parts will be suggested to one skilled in the art hence I do not wish to be limited to the precise structure and combination of parts herein described.

'lVhat I claim is:

1. In a mechanism of the class described, a vertically disposed guide for a column of insert washers, a movable member normally supporting the column of insert washers and having means therein adapted to-register with the lower end of said column to release the lowermost washer-insert when the said member is moved toward said column, and a member secured to the movable member and adapted to be moved thereby toward, and into, said column immediately above the lowermost washer-insert prior to the release of the latter washer-insert.

2. In mechanism of the class described, a vertically disposed guide for a column of insert washers, a slide normally supporting the said column and having an aperture therein adapted to be brought, when the slide is moved, into register with the lower end of the column for releasing the lowermost washer-insert and a member secured to the slide and adapted to be projected thereby into the said. column immediately above the lowermost washer-insert prior to the release of the latter washer-insert.

3. In a mechanism of the class described, a base having an aperture therein, a guide for a column of washer-inserts suspended in said aperture, a slide movably mounted on Athe base and normally supporting the said column of washer-inserts, the slide having an aperture therein adapted to be brought into register with the aperture in the base and with. the lower end of said column for releasing the lowermost washer-insert, the guide extending through the aperture in the movable slideand means carried by the slide and adapted to be moved into the saidv column washer-insert for temporarily supporting the portion of said column above the same.

4., In mechanism for feeding washerinserts to heel-molds, the combination of a vertically disposed guide adapted to receive a column of stacked washer-inserts, a fixed member having an aperture therein concentric with the guide, a movable member on the fixed member normally supporting the washer-inserts and having therein adapted to be moved into register with the aperture in the fixed member for releasing the lowermost washer-insert, and a member secured to the movable. member and overhanging the aperture therein and adaptl ed to enter the column of washer-inserts between the lowermost washer and the washer next above prior to the release of the said lowermost washer.
